Put spaces between the words in string

Put spaces between the words in the string

• We can append between the words in the string using the methods available in the Character class and also by using the split method.
• After adding spaces convert the string to lowercase.

Example:

Input:      KeeplearnersBlogspotCom

Output:   keeplearners blogspot com

Program:

public class PutSpacesBtwWords {
    public static void main(String[] args) {
    String str = "KeeplearnersBlogspotCom";
    System.out.print("Given Input String=" + str);
    String newStr = "";

    for (int i = 0; i <= str.length() - 1; i++) {
        if (Character.isUpperCase(str.charAt(i))) {
            newStr += " " + str.charAt(i);
        } else {
             newStr += str.charAt(i);
        }
    }
    newStr = newStr.toLowerCase();
    System.out.println("\nPut spaces between words starting with capital letters=");
    System.out.print(newStr.trim());

    String[] arr = str.split("(?=[A-Z])");

    String finalStr = "";

    for (String s1 : arr) {
        finalStr += s1 + " ";
    }
    System.out.println("\nPut spaces between words starting with capital letters using split=");
    System.out.print(finalStr.toLowerCase());
    }
}

Output:
Put spaces between the words in string
